I just used a complete PS CS5 self-study manual, which is quite detailed to tell the truth, but the video tutorial inside is too rigid, step by step according to the effect it wants to achieve, like some questions: Why do you use this data? Can you change the data? Can we not set this? . It is very confusing for a novice like me, but I will only tell you that following him can achieve this effect. In contrast, some good network lecturers are relatively flexible. It is suggested that they study together ~ I wish my friends an early learning ~
